Resumen
Se realizaron evaluaciones electroquímicas de derivados del 2-mercaptoimidazol y de sustancias activas de medicamentos (como los supresores de secreción gástrica) como inhibidores de corrosión en condiciones estáticas e hidrodinámicas del acero API 5L X52 inmerso en medio acuoso de HCl 1 M mediante las técnicas de Espectroscopía de Impedancia Electroquímica (EIE), obteniéndose la mejor eficiencia (de ~90 %) desde bajas concentraciones y en condiciones estáticas. Se detectó mediante un electrodo de disco rotatorio que a 40 rpm se mejora ligeramente la protección contra la corrosión. Al aumentar las revoluciones por minuto, de 100 y 1000 rpm, la eficiencia de inhibición tendió a disminuir (como resultado del proceso de adsorción-desorción de las moléculas orgánicas por la velocidad de rotación). Se demostró que el pantroprazol se mantiene activo y protege al acero hasta tiempos de inmersión cercanos a las 700 horas. Finalmente, los supresores de la secreción gástrica presentaron un mecanismo de adsorción de fisisorción sobre la superficie metálica empleando la isoterma de Langmuir.
